美颌龙属

美颌龙约有公尺长。分别为:成年法国标本(橘)、幼年德国标本(绿)
于1850年代在德国巴伐利亚发现的美颌龙化石。这是存放在牛津大学自然史博物馆的塑像。化石保存在颗粒细致的石灰岩板中,该个体死后萎缩,导致颈部后弯,部分指骨四散。
在法国发现的美颌龙化石

美颌龙属(学名:Compsognathus)又称细颚龙细颈龙新颚龙秀颚龙,是一属小型的双足肉食性兽脚亚目恐龙。牠约有火鸡的大小,生存于晚侏罗纪提通阶早期的欧洲,约1亿5000万年前。古生物学家已发现两个保存良好的化石,一个于1850年代在德国发现,另一个是在将近一个世纪后于法国发现。美颌龙是几类确知其食性的恐龙之一,在两个标本的体内都有小型的蜥蜴化石。在葡萄牙发现的牙齿有可能也属于美颌龙。牠的名字是来自古希腊文的「κομψος」(意即美丽)及「γναθος」(意即颚或颌)。

美颌龙的两个化石都是较为完整的骨骼。目前的已承认种只有长足美颌龙C. longipes)。不过,在1970年代于法国发现的较大标本,曾被认为是另一个种,而被命名为C. corallestris。德国标本目前被发现是个幼年个体,两个标本属于相同物种。在1980年代及1990年代以前,美颌龙曾被认为是最小型的恐龙,并且是始祖鸟的近亲。因此,美颌龙是在古生物学之外,广受一般大众熟悉的恐龙之一。

Evidence from related species suggests that the body might have been covered with feather-like structures.
Joseph Oberndorfer acquired this fossil in Bavaria, Germany, in 1859. Shown here is a cast at the Bavarian State Institute for Paleontology and Historical Geology

Compsognathus (/kɒmpˈsɒɡnəθəs/; Greek kompsos/κομψός; "elegant", "refined" or "dainty", and gnathos/γνάθος; "jaw") is a genus of small, bipedal, carnivorous theropod dinosaurs. Members of its single species Compsognathus longipes could grow to the size of a turkey. They lived about 150 million years ago, the Tithonian age of the late Jurassic period, in what is now Europe. Paleontologists have found two well-preserved fossils, one in Germany in the 1850s and the second in France more than a century later. Today, C. longipes is the only recognized species, although the larger specimen discovered in France in the 1970s was once thought to belong to a separate species and named C. corallestris.
